Description
(Fig. 35)
Material examined: 10 larvae deriving from 10 females.
Larvae medium-sized: idiosoma 190–212 µm long.
Dorsum: Dp relatively small (DpL: 170–194 µm; DpW: 146–170 µm), egg-shaped, widest at about 1/3 distance from anterior margin; distinctly narrowing posteriorly; posterior margin rounded. Antero-lateral indents relatively shallow, obtuse-angled, about 1/5 and 1/4 of Dp length and width, respectively. Microrelief cells elongated. DpW/Mp1-Mp1 5.0. Lp2, Mh1 smooth. Mp1-Mp1 short (30–34 µm), shorter than Mp2-Mp2 (38–46 µm); Mp1-Lp2 intermediate (38–42 µm). Venter: CpIm (68–72 µm) clearly longest, CpIIm shortest (22–28 µm) and CpIIIm intermediate (40–46 µm). CpIm:CpIIm:Cpm ratio 2.8:1:1.7. Setae on Cp smooth, relatively thick and long. C1-CpIm (21–26 µm) identical to or somewhat longer than C4-CpIIIm (21–22 µm). C1-C2 moderately long (40–45 µm). Expp triangular, margins convex, width almost equal to length. Exp located distinctly below plate’s mid-point and slightly below E2. Palps: PIII 1 bipectinate. Chelicerae: First segment cylindrical (73–77 µm), narrowing anteriorly, one margin straight or somewhat concave, other slightly convex. Legs: Somewhat shorter than body; LI<LII <LIII (Fig. 3). ITi7 thick; ITi8 long; IITi8 long, smooth, thin; IITi10, IIITi10 located at centre of tibia; IIITa3 located near centre of tarsus.
